Application filed March 29, 1918. Serial No. 225451.

To all whom it may concern Be it known that I, LEONARD E. JENKINS, a citizen of the United States, residing at Bayfield, in the county of La Plata, State of Colorado, have invented a new and useful Measurin Device for Gasolene-Pumps; and I do here y declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. I

This invention relates to an improved measuring device for use in connection with gasolene pumps of the type that are em-", ployed'in garages and automobile filling sta-. tions, and an object of the invention is to provide a device of this kind, for so measuring the gasolene up to five gallons by half I gallons when pumped, that the chaufieur in the car may see theexact amount that has been purchased, aspwell as the person whojs operating the pump.

A .further object of the invention is to provide a supporting tlfiinder carried by the outlet pipe of the v p, for supporting an inverted gasolene receptacle, for. instance an open ended bottle.

A further object of the invention is the provision of means for centering the bottle 80 or receptacle. in the supporting. casing or cylinder.

A further object of the invention is the.

provision of means for permitting air to enter the receptacle, whereby gasolene may easily flow from the receptacle when the outlet valve is open.

In practical fields the details of construction may necessitate alterations falling within the scope of what is claimed.

The invention comprises further features and combination of parts as hereinafter'set forth, shown in the drawings and claimed.

In the drawings Figure v1 is a view in side elevation of a filling-station gasolene pump. showing the measuring device as applied thereto.

Fig. 2 is a vertical sectional view through the measuring device.

Fig. 3 is a sectional view on line 33 of Fig. 2.

Fig. 4 is a detail perspective view of a rubber gasketthrough which the terminus of the outlet pipe of the pump extends at the point where the terminus enters the 65 gasolene receptacle.

an elbow'fZ. The section o nected by an elbow 8 to. 3, which is coupled at The casing 5 is hollow a has a conical upper en 1 opening 11 therein is threaded, tubular section 12 is threaded, lar section is also threadedgin as shown in Fig. 2. Secured: face of the lower end of th g 5 y rivets 13 are angular supporting, arms. 4,'the' lower ends of which aresecuredby rivets 15 to the tubular connector y y H cylindrical wall of thei-enl rgement. 17. the connector has threadsJSlQiAQgaSoIene receiving receptacle 19 is;,larranged in the casing 5 and the contractediie'ckor'-,,olit1etL- 8To end 20 of the receptacle ,1 (whichjisfin verted) is threaded into the"enlargementllnj ofsaid connector, there being a, washer; 21.1"

in the enlargement againstij chthe ginal edge of the outletendciiga 'esto intube 23 is connected. The flexible tube has. an angular outlet member 24 at its end to extend into the gasolene tank fillin opening (not shown) of the automobile. llllhere the neck merges from the body of the receptacle 19.an' annular shoulder 25 is provided. A rubber gasket 26 surrounds the receptacle 19 and is in engagementwith the shoulder 25 and designed to hold the receptacle spaced centrally of the casing or cylinder 5, as shown in Fig. 2. The end wall 27 of the receptacle 19 has a countersink 28, and the bottomof this countersunk portion has an opening '29 through which the tubular section 12 extends loosely. A rubber gasket or washer 30 is arranged in the countersink,

its surfaceprovided with vertically extending corrugations 32, which are engaged by the tubular section 12, so as to hold the receptacle centered or concentric with the easing 5, and by means of the spaces between the corrugations sufiicient air is allowed to enter the receptacle, whereby the displace- The in'teriqrv slot 34 is a scale 35 graduated in gallons.

from one to five, while the gallons are su-\divided in quarts and half gallons, By means of this graduated scale the'exact amount of g'asolene as it is allowed to enter the recap,

- tacle 19, may beread by the chaufli'eur in the automobile, as well as by the attendant who operates the pump at the filling station. The amount of gasolene purchased is allowed. to enter the receptacle, and then the valve 22 is opened, whereby the gasolene may'em ter the tank of the automobile.

The inventionhaving been set forth what is claimed as new and useful is 1. In a measuring device for gasolene dispensing pumps, a supporting casing having a graduated scale, a pipe connected at its extremity with said casing, the lower end of the casing having a connector depending therefrom, a discharge pipe coupled to the connector and provided with 'a valve, a receptacle, having a lower contracted neck engaging in and supported by the connector, and a pipe of communication between the first named pipe and the upper end of the receptacle,

2. In a measuring device for gasolene d1spensmg pumps, a supporting casing having a graduated scale, a pipe connected at its eX- tremity with said'casing, the lower end of the casing having a connector depending therefrom, a discharge pipe coupled to the connector and provided with a valve, a receptacle havinga lower contracted neck en gaging in and supported by theconne tor, and a pipe of communication between. the first named pipe and the upper end of the receptacle, and means at both ends of the receptacle for holding the receptacle supported concentrically in the casing. 3. In a measuring device for gasolene dispensing pumps, a supporting casing having a graduated scale, a pipe connected at its extremity with said casing, the lower end of the casing having a connector means comprising angularly depending arms from the casing for supporting the connector, a discharge pipe coupled to the connector and provided with a valve, a receptacle having a lower contracted neck engaging in and supported by the connector, and a pipe of communication between first named pipe and the upper end of the receptacle, means at both ends of the receptacle for holding the receptacle supported concentrically in the casing, and means adjacent the pipe of communication to'permit air to enter the receptacle, the top of the casing having apertures.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
